Brett Butler joins Charlie Sheen on new FX show

This either has the potential to be a brilliant pairing — or a colossal hot mess. EW has confirmed that Brett Butler will join Charlie Sheen’s upcoming FX comedy Anger Management.

In the show that will premiere June 28, Butler will play a bartender at Sheen’s favorite haunt. The sitcom is loosely based on the 2003 movie of the same name from Joe Roth’s Revolution Studios and will be written and executive produced by veteran comedy writer Bruce Helford (The Drew Carey Show).

Butler and Sheen have one very big thing in common: Both worked on sitcoms from uber-producer Chuck Lorre and both managed to generate critical praise — and negative headlines — for their work as headliners. Butler was the bombastic star of Grace Under Fire from 1993 to 1998 on ABC, and, well, who doesn’t know how Sheen spent his last decade?

Butler fell off the radar for some time before claiming during an interview recently that she briefly lived in a homeless shelter. She’s been attempting to stage a comeback by doing standup in Garrett Morris’ comedy club in downtown Los Angeles.
